.4 My invention relates to improvements in voice mechanisms and more particularly to devices adapted to be inserted in dolls or toys whereby sounds may be issucd there- :3 from in simulation of the wo-rds pa-pa, ma-ma .etc. The main object of the 111 vention is to provide an arrangement which is not only self-contained butiis simple and eflicient in operation and inexpensive in con- W struction. Further and more specific objects, features, and advantages. will more clearly appear from the detail description given below taken in connection with the accompanying sheet of 'iormsa part of this specification,

Extending up through the disk!) is a flat metal post 10, the lower endof which is bent laterally as at 11 and lies within a cutaway portion on the lower side of the disk 9., A thin pasteboard disk 12 isqpasted m erthe bottom of the disk 9 and extension 11 and over this isplaceda pasteboardor metal. cap 13 having its edges flanged as at 14 to extend a short distance upon the outside of the cylindrical; casing 5.
